actually I am not convinced this is the right fix. Adding random driver
flags and hoping that it makes them works is a bad idea. The BCM92035
was one specific behavior to switch HID proxy mode into working dongle,
but that is ancient behavior. These days just HCI_Reset is enough for
Broadcom dongles.
Also the fact that it still does not complete work makes me highly
suspicious that this fix is actually wrong. And without having seen the
hcidump's for the failing pairing, I would not bother here at all.

Marcel
